4 Making A Difference

5 Manufactured Homes Overview Definition: Single-story, constructed in a factory, wood-frame bolted to steel chassis, designed to be transported.

6 Manufactured Homes Overview 6% of all single family households in U.S. 19 million people occupy 9 million mobile homes Lower energy standards than site-built homes not updated since 1994

7 Why target manufactured homes?

8 Underserved Market The manufactured housing market requires a targeted, separate program with low delivery costs to capture energy savings and affect utility bill non-payment.

30 Customer Feedback My furnace doesn t run so much, and the heat seems to be more evenly spread out. I keep the heat set at 68 degrees and the house feels warmer. Instant relief from the dust and cold. Much warmer with the heat turned down. The new showerheads they put in are nice. Bills went down! Light bill

31 Pilot Results Michigan (MECA/SEMCO) Wisconsin (Focus on Energy) Participants 63 - met goal 79 - exceeded goal No duct sealing 5 2 Total Annual kwh 41,818 kwh 117,020 kwh Total Annual therms 9,603 therms 3,823 therms Avg Annual kwh/home 664 kwh 1,481 kwh Avg Annual therms/home 152 therms 48 therms Note: Billing analysis to be completed Q

32 Future Considerations Community engagement and recruitment Contractor training is valuable Customer intake/scheduling process Homes have multiple bathrooms Geography matters To increase electric savings: o Target homes with electric water heaters o Include ECM and outdoor LEDs to increase average kwh savings per home

33 Benefits Reduced Billing Arrears and Shutoff Community Engagement Workforce Development Demand Reduction Utility Benefits Economic Development

34 Next Steps Launched as a program in Michigan 2016 Utility billing analysis for both pilots in Q Explore different program approaches
